[ADAU1452] Internal PU/PD States During and After Reset

Thread Summary

The user inquired about the state of internal pull-up/pull-down resistors during and after reset for the ADAU1452. The support engineer provided a spreadsheet detailing the default pin states in and out of reset for the ADAU145X family. For the ADAU1463, the reset value of the Multipurpose Pin Mode Registers, which set the pull resistors, is 0x0000.

Hi,

We have a question regarding the status of the internal pull-up/pull-down (PU/PD) resistors during and after reset for the ADAU1452.

Upon checking the ADAU1452 datasheet, we found a reference to internal pull resistors.
Please refer to "Table 26. Pin Function Descriptions" (Page 23).
Is the state of the internal pull-up/pull-down resistors the same during and after the reset?
If the state differs, please provide details.

Best regards.
